To own a house. To not be on abject poverty as I grow old. Two goals that should not be this hard, except we are now in a society of rich and poor and I'm not rich, I'm poor.
May I ask why you want to own a house? I am kind of realizing that the majority of people in the world do not own a house.
Because then it's yours. If all else fails you have 4 walls and a roof over your head. Also it's not fair to compare an individual to the rest of the world due to the large and varied place that it is.
But in the US, some people argue that the house is not completely "yours" - if you don't pay your (ever increasing) real-estate taxes, the house may be taken from you.
